Restless legs syndrome (RLS) is a common chronic sensory motor disorder that prevents initiation and/or sleep staying. Patients with this syndrome have uncomfortable sensations in their legs (and sometimes arms or other parts of the body), with moving their legs to relieve this sensations. The symptoms of RLS are usually worse in the evening and at night. The diagnosis of RLS is primarily based on clinical evaluation and clinical history of the patient. International restless leg syndrome group study (IRLSSG) evaluates the symptoms and severity of RLS. RLS can be divided into two groups of primary and secondary. Iron deficiency, Parkinson’s disease, kidney failure, diabetes, peripheral neuropathy, and pregnancy may cause RLS. Antinausea, antipsychotic drugs, some antidepressants, and antihistamines may also worsen the symptoms. RLS is also observed in chronic obstructive pulmonary disease (COPD), which makes the outcomes worse. COPD is a main preventable health problem that can lead to morbidity and mortality. Thus, RLS in COPD causes excessive daytime hypersomnolence, fatigue, poor quality of life, disability and neuropsychological complications such as social isolation, frequent daytime headaches, anxiety and depression.
